-subalgebras of so(17), type
Number of sl(2) subalgebras: 85.
Let
be in the Cartan subalgebra. Let
be simple roots with respect to
. Then the
-characteristic, as defined by E. Dynkin, is the
-tuple
.
The actual realization of h. The coordinates of
are given with respect to the fixed original simple basis. Note that the
-characteristic is computed using
a possibly different simple basis, more precisely, with respect to any h-positive simple basis.
A regular semisimple subalgebra might contain an
such that it has no centralizer in the regular semisimple subalgebra, but the regular semisimple subalgebra might fail to be minimal containing. This happens when another minimal containing regular semisimple subalgebra of equal rank nests as a root subalgebra in the containing subalgebra. See Dynkin, Semisimple Lie subalgebras of semisimple Lie algebras, remark before Theorem 10.4.
The
submodules of the ambient Lie algebra are parametrized by their highest weight with respect to the Cartan element
of
. In turn, the highest weight is a positive integer multiple of the fundamental highest weight
.
is
-dimensional.

Length longest root ambient algebra squared/4= 1/2
Given a root subsystem

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation.

More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element.

More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation.

More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens
here.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens
here.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens
here.

More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens

More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens
here.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens
here.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens
here.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens
here.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens
here.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens
here.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens
here.

More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens
here.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens
here.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens
here.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens
here.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens
here.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens
here.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens
here.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens
here.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation.

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens

Starting h, e, f triple. H is computed according to Dynkin, and the coefficients of f are arbitrarily chosen.
More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element. Whenever a hard-coded coefficient is used, it was selected so it results in fast computations. The selection was discovered through manual experimentation. As of writing, the arbitrary coefficient selection happens
here.

More precisely, the chevalley generators participating in f are ordered in the order in which their roots appear, and the coefficients are chosen arbitrarily. More precisely, the n^th coefficient either 1) equals (n-1)^2+1 or 2) equals a hard-coded number that is specific to the given ambient Lie algebra, dynkin index and h element.
